The Bofors 57mm naval gun is designed to address surface, air, and land threats in the littoral environment, and is already in service with a wide range of navies and coast guards, including those of the United States, Canada, Sweden, Finland and Mexico.

With a length of 60 meters, the KCR-60 was designed to quickly deploy guided anti-ship missiles against surface combatants and then rapidly and safely withdraw into the region’s archipelagos. Three KCR-60 vessels are currently in service with the Indonesian Navy, Tentara Nasional Indonesia-Angkatan Laut, or TNI-AL, with a fourth ship scheduled to be operational in 2021.

Two of the new 57 Mk3 systems will be for two KCR-60 vessels currently under construction, while the remaining two guns will be integrated onto two existing KCR-60 ships. The gun systems will be produced at BAE Systems facilities in Karlskoga, Sweden. The first unit is scheduled for delivery in 2020 and the final unit in 2021.
